Leslie's CYA test also is unlikely to be able to tell 100ppm CYA from 200ppm CYA.

If your water's new, How did it get so much CYA in it?
Note to self......dont trust Leslies. I stopped on the way home at Walmart and picked up the 6 way test. Heres the results I got.

CL 5 PPm
PH 7.6
ALK 150
Hardness 120
CYA 40 PPM


Borax 45 PPM Not tested (but I know how much I put in)
